These are a few of what I've acquired so far. I've gotten a few more since this picture My thanks to rent on helping me acquire all but two of these. As a matter of fact I think rent helped me with everyone of these suppressors in this picture. I highly recommend rent for all your firearms needs You could not ask for a better person.

From left to

GRIFFIN RSTA both of these OTB suppressor are great reduced blow back extreme accuracyGRIFFIN SPR refer to above. Oh yeah the RSTA 308 will fit the 5.56 SPR mounts to shoot on 5.56 rifles.

SICO HYBRID this suppressor is just an all around fantastic suppressor. It's as quite as any of the ones I own when compared. The HYBRID is just a great suppressor. Rated up to 338 Lapua Win Mag. I guess that's why it's on the heavy side.

GRIFFIN RESISTANCE 9MM good but the TI RANT 9mm. was not avail when I ordered if it had been I'd gotten it instead

SICO WARLOCK 2 .22 cal. FANTASTIC..22 cal suppressor extremely quite and no first rd pop. Very small and lite. The ONLY THING I hate about this suppressor is its ALL ALUMINUM CONSTRUCTION

GRIFFIN ALPHA 308 this one can be disassembled for cleaning plus the end cap can be changed out to .22 cal or 308 cal. This is a fantastic suppressor

NOTES
I really am a hugh fan of the TAPERED MOUNTS after using them. They will not come undone. The ONLY THING with a TAPERED mount is you must let them cool down some before they will let go of the mount. You will unthread your barrel mount before it will come undone if you do not let it cool down some.

Also on the SCAR 17 you MUST USE A BARREL SHOULDER RING when putting on the barrel suppressor mount. NOT INDEXING SHIMS but a barrel shoulder ring of some kind. Something similar to the KBA Custom SCAR 17 Shoulder Ring. If you do not you'll have problems and could damage your suppressor. You'd still use the indexing SHIMS over the shoulder ring if installing a break.

Oh yeah the RSTA suppressor will fit the SPR mounts. If you have both suppressor DO NOT GET CONFUSED AND PUT YOUR SPR 5.56 SUPPRESSOR ON YOUR 308 RSTA MOUNTED WEAPON AND SHOOT IT.
I've not done that but I can see where that could happen because the SPR will fit the RSTA mounts.

But if you just wanted one OTB suppressor the RSTA would work on your 5.56 it's just a little fatter and longer but remember....its an OVER THE BARREL SUPPRESSOR it'll still not add as much length as some 5.56 suppressor would. You can see the difference between the two above. They are the first two on the left
